Given numbers are 538, 370, 645, 800

The list of prime factors of all numbers are

Prime factors of 538 are 2 x 269

Prime factors of 370 are 2 x 5 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 538, 370, 645, 800

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(538, 370) = 99530

GCD(538, 370) = ( 538 x 370 ) / 99530

= 538 / 370

= 538

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

So, Greatest Common Divisor of 538, 370, 645, 800 is 1
